Discovery: The great whale pee funnel moves vital nutrients

Scientists have discovered that whales move nutrients thousands of miles -- in their urine -- from as far as Alaska to Hawaii. These tons of nitrogen support the health of tropical ecosystems and fish, where nitrogen can be limited. They call this movement of nutrients a 'conveyor belt' or 'the great whale pee funnel.' In some places, like Hawaii, the input of nutrients from whales is bigger than from local sources. It's critical to tropical oce…
